Tire Selection for 987.2 Base Boxster - 2009 MY 17" Rims

[JayG]

I would go with 225/45-17 front and 255/40-17 rear(or even 245/40)
the wider front gives you more grip and better balances the car

Also look at Pilot Super Sports, its a better tire then PS/2


*******
fixed the size. Should be 225/45, not 225/34
fat fingered it

Thanks y'all. Going wide - what are the disadvantages?

Would these touch the fender inserts if turned lock to lock?

I suppose since the outside diameter may not change, it will not impact either bump stops or any suspension components? Also, any change in the speedometer reading?

My rims are standard 17" - 7 J X 17 H2 with 55 mm offset up front and 17" - 8.5 J X 17 H2 with 40 mm offset back rear.

Thoughts?

I run 225/45-17 and 255/40-17 without any problems
As far as speedo, well to my knowledge, all of our cars read a few MPH high anyway.
Most 225/45 and 255/40 are the same diameter 255/40 is the factory size so there shouldn't be any speedo change over factory
